Someone who is known for constantly backing out on plans ("flaking"), often for reasons that are flimsy and/or somewhat insulting ("frosty").
"My friend was supposed to come visit me in the hospital after my round of chemo, but then she called at the last minute to say she couldn't afford to waste her gas on the drive up. I don't know what I was expecting anyway, she's totally frosted flakes."

A person that makes plans with you then they alway bail last minute but they sugar coat their excuse so you forget how flakey they are so you keep making plans with them.

Jessica wanted to use Head and Shoulders anti-dandruff on her vag but I suggested we try getting kinky by frosting her flakes. After I was done I suggested Frosted Flakes to a good friend who also had dandruff
